SPRINGFIELD – Springfield police said they arrested a city man and a resident of Rochester, New York, Wednesday as officers interrupted a drug deal outside a State Street convenience store, seizing 300 packets of heroin and more than $1,600 in cash.

Each was charged with possession of heroin with intent to distribute, violation of a drug-free school zone and conspiracy to violate drug laws.

The arrests mark the second time in less than 24 hours that police seized at least 300 packets of heroin. Narcotics detectives on Tuesday night arrested three people during simultaneous raids at two residences on Eastern Avenue and one on Melrose Street.

Figueroa and Lopez were arrested in the parking lot of the Day and Night convenience store, 671 State St., by narcotics detectives under the command of Lt. Charles Cook, Delaney said.

Police had learned of a possible large drug transaction at the parking lot and moved in just in time to interrupt the exchange, Delaney said.

Figueroa and Lopez were scheduled to be arraigned Thursday in Springfield District Court. Arraignment information was unavailable.
